T0 a/ZZ whom t may con/cern:

Be it known that we, LAUREN E. CRANE and THERON H. BLY; citizens of theUnited States, residing at Minneapolis, in the county of Hennepin andState'of Minnesota, have invented certain new and useful Improvements inSmoke-Ejectors; and we do hereby declare scription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention has for its object to provide an improved apparatus for ejecting smoke or fumes by im ulses and preferably in the form of rings;an it consists of 'the novel devices and combinations hereinafterdescribed, and defined in the claims. v

The ap aratus is adapted to take different forms and) is adapted for agreat many different uses. For instance, it is especially well adaptedfor diffusing disinfecting, germ an insect destroying smoke and fumes,and it isalso adapted for use as a toy or advertising medium forshooting smoke rings into the air, all as will be hereinafter more fullydescribed. y

The invention is illustrated in the accompanying drawings, whereinv likecharacters indicate views. A

Figure 1 is a view in side elevation, showing the im roved apparatus inthe form of a cannon. ig. 2 is a vertical section taken centrallythrough the a paratus shown in Fig. 1 from front to rear t ereof, andFig. 3 is an enlarged* transverse vertical section taken .through thedevice on the line x3 m3 of Fig. 2.

Referring first to the construction illustrated in Figs. 1, 2, and 3,the numeral 1 indicates the barrel of the'toy cannon, the same beingrigidly supported by a box-like base 2. The numeral 3 indicates adrawer-like fireboX which is removably fitted into a compartment 4 inthe upper forward ortion of the base 2. This fire-box is provi ed with aperforated false bottom 5, below which is an air-inlet duct 6. 'Thecompartment 4 opens into the barrel 1 througha plurality of perforations7, as best shown in Fig. 2. These passages 7 permit the smoke from theburn-y ing material z, contained within the fire-box 3, to pass upwardinto the intermediate portion of the barrel 1. The extreme outer end ofthebarrel 1 is provided with a con-` like parts throughout the several.

perforations 7, is a yielding diaphragm 9, preferably constructed ofthin spring metal and secured to the barrel only at its upper portion,so thatits lower portion is free to vibrate. In the barrel 1, slightlyrearward of the diaphragm 9, is a crescent-shaped flange 10,- which issecured to the lower portion of said barrel. passage of air betweenv thebarrel and the loose portionI of the diaphragmQ.

Mounted on a frame 12 secured within the base 2, is a spring-motor,(indicated as an entirety tor may be of the usual or any suitableconstruction, but is arranged to im art rotary motion to a wheel or disk14, whic has a plurality of laterally-projectingcircumferentially-spaced cam-pins-15. Mounted in the u er portion oftheframe 12 is a short rockshaft 16, which carries anu wardly-project Thehammer 17 projects upward through the perforation 11 of the barrel 1,and its head stands in position to strike against the diaphragm 9,approximately at its center. A s ring 19, attached to the hammer 17 andto t e frame 12, tendsto force the head of the hammer' against the saiddisk. The lower end of the trip-arm 18 stands in position to be engagedin succession b the cam-pins 15 of the motor-driven whee 14. As shown,the spring ofthe motor 13 is ada ted to be wound in the usual Way orafter the manner of an ordinary clock -spring by means of a key 20. j

As vis evident, when the spring-motor is tated the cam-pins 15 comininto en agement with a trip-arm 18 will orce the ammer 17 away from theldiaphragm 9 and then upon passing out of 'engagement with said arm willrelease the hammer and ,permit the head thereof to be thrown againstvthe diaphragm by the spring 19. In this way the diaphragm will bev'brated with sudden impulses and for eachimpulse will eject from thebarrel 1, through the contracted nozzlepassage 8, a puff of smoke which,as has been found in practice, will take the form of a tice that foreach time the diaphragm 9 is struck by the hammer it will make two, andsometimes three, vibrations, thereby frequently ejecting two and threesmoke-rings in very rapid succession. When this toy cannon is thus putinto action and caused to ing hammer 17 and a depen ing trip-arm 18.-

1 An apparatus of the kind described, comprising ya barrel and a hollowbase having the general appearance of a cannon, of a ldiaphragm Within'said barrel, ahammer for Striking said diaphragm, mechanism locatedwithin said base for actuating said hammer, and means for producingsmoke within saidl barrel, substantially as described.
